After I interviewed Nadav Caine, author of Mathematic-Tac-Toe, he found the disks for Quote Blaster. Quote Blaster is an unpublished educational game for the Atari 8-bit computers, that he talked about in our interview. His intention was that it would be published by Atari Program Exchange, but APX closed up shop before he was done.
One of the disks is dated November 1984. The disk images are attached, and some screenshots. There are several versions of the game across two disks. It looks to me like it started life as Quote Blaster, then he renamed it to Tribunal.
